If the Church errs then how is it the pillar and bulwark of truth? Talk about a weak bulwark.
We are also children of God, yet we are sinners. It is the same explanation for both. I am a child of God because he has gifted me faith through grace, yet have not been purified of my sins. Equally, the Church is the pillar and bulwark of truth because it proclaims the mystery of faith, yet it has not been purified of sins. The atonement has been completed, and now we sinners, as the Church, proclaim the mystery of faith: "Christ has died, Christ is risen, Christ will come again." THAT is the pillar and bulwark of truth. And it's in both our masses.
Peter personally erred, yes of course he did. But the Church as an institution does not err on matters of faith and morals. The pope does not err when teaching authoritatively on matters of faith and morals.
What arrogance! If the pope is a sinner, then all parts are subject to corruption, including teachings on faith and morals. I will say that you Romanists are often correct, but you are certainly not perfect. The magesterium has never corrected the animism of South America, the Philippines, and the like. Those Romanists aren't Trinitarian, they're henotheistic and overly superstitious. If your magesterium was truly so infalible, how could it, with it's perfect understanding, never address these abuses? And let's not even start on purgatory, Mary, and justification via works.
Yet Christ was very explicit about building this institution on Peter.
Obviously not, ergo the Great Schism, ergo Protestant Reformation, ergo political usurpation of the Pope as the head of the Christian world. Plus, Peter was a Judaizer for a time! How can the pope be a heretic and perfect in faith and morals? Do you not remember when Paul had to publicly chastise Peter?
And a church that errs is a sign of a false church.
Yes, and neither your church nor mine has declared anything separate to "Christ has died, Christ is risen, Christ will come again." They are the one and the same. Extra-Doctrinal differences are meaningless. To say otherwise is Gnosticism, therefore heretical.
You're misconstruing my argument. I never argued that anyone person is impeccable. All I said is that the Church as an institution when teaching faith and moral authoritatively cannot err. It cannot teach false doctrine. Otherwise, what good is a pillar and bulwark of truth if it constantly fails?
Then are popes, when teaching faith and morals, impeccable? I argue no. No person is, any circumstance, impeccable until Christ comes again.
